Subject [jira] [Commented] (LUCENE-3496) Support grouping by IndexDocValues
Date Fri, 07 Oct 2011 20:24:29 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-3496?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13123147#comment-13123147

Yonik Seeley commented on LUCENE-3496:
--------------------------------------

Wow, only a 9% performance penalty for not keeping the values in the JVM heap?  That's quite
an achievement (and almost hard to believe, unless the base query were really expensive or
something).  Nice job!

> Although IDV is not yet finalized (More particular the SortedSource). I think we already
can discuss / investigate implementing grouping by IDV.
